Ns2 simulation project code
In our site students can get recent IEE based networking projects. We have our firm foot in network simulation over seven years. Our staffs are expert in implementing networking projects. Ns2 simulation project code provides substantial support for simulation of TCP, routing algorithms, queuing algorithms, and multicast protocols over wired and wireless (local and satellite) networks, etc. Ns2 simulation project is freely distributed in nature and all source code is available in our site.
This Ns2 simulation project code site offers network simulator based projects on the following areas: Mobile Ad hoc Networks (MANETS), Wireless Sensor Networks (WSNs), Heterogeneous Networks, Wireless Mesh Networks (WMNs), Cognitive Radio Networks, Vehicular Ad Hoc Networks (VANETs), MAC layer performance & Quality of Service (QoS) Enhancements, IEE 802.11, IEE 802.15, IEE 802.16 etc.
In the following we are discussing about these three schemes. The node has moved a given distance d when a node transmits a beacon in the distance-based beaconing. The node does not hear any beacons from the neighbor when the node removes an outdated neighbor. Since the node has moved more than k-times the distance d, or after a maximum time out of 5 s in a distance based beaconing. Therefore, this distance based beaconing approach is adaptive to the node mobility. For example a faster moving node sends beacons more frequently and vice versa. However, this approach has two important problems. First, many outdated neighbors had by a slow node in its neighbor list since the neighbor time-out interval at the slow node is longer. Second, the fast node may not detect the slow node when a fast moved node passes by a slow node due the infrequent beaconing of the slow node. The perceived network connectivity is reduced by its infrequent beaconing of the slow node.
An adaptive position update is proposed in our Ns2 simulation project code. By listing the assumptions made in our Ns2 simulation project code work:
1. All nodes are aware of their own position and velocity in Ns2 simulation project code
2. All links are used in Ns2 simulation project code is bidirectional.
3. The current location and velocity of the nodes are called beacon updates, and
4. Data packets can piggyback position and velocity updates and all one-hop neighbors operate in the promiscuous mode and hence can overhear the data packets in Ns2 simulation project code.
Each node broadcasts a beacon informing upon initialization its neighbors about its presence and its current location and velocity. Periodically, each node broadcasts its current location information in most geographic routing protocols such as GPSR when following this Ns2 simulation project code. Each node stores the position information received from neighboring beacons. Continuously, each node updates its local topology based on the position updates received from its neighbors in a network. The neighbor list is represented by its local topology. The neighbor lists are considered only those nodes as possible candidates for data forwarding. Thus, an accurate representation of the local topology is maintained by the beacons which play an important part in the Ns2 simulation project code.
Advantages of Ns2 simulation project code:
The network throughput is increased.
The packet delivery ratio is also increased when using Ns2 simulation project code.
The network delay is reduced by using Ns2 simulation project code.
